Saw this sliding mitre saw on the shelf at my local B&Q in Durham, caught my eye has it had a very long slide on it, so can cut upto 340mm.
Also had double bevel meaning you can cut angles from both sides - I've got a cheap Evolution one so not got this feature, but think it would be handy as you can then cut through the face of your work for skirting etc.
Seems very cheap at £92, takes standard 30mm bore blades unlike the Evolution. No idea if any good or accurate as it says its a special edition so hard find on google. This model looks very similar though:
